Sometimes when the groups are uneven the raid frames align incorrectly. This happens in v3 and v4.

Seeing this also on latest 4.x version. Occurred when people left the raid.

Can confirm this issue occurs frequently when unfilled raid groups get shuffled around with the latest version.

Does this happen on a fresh profile aswell?

Sorry for the delayed response. I cannot get this to be replicated with a fresh settings file. Probably should just close this and recommend removing their LunaUnitFrames.lua file if someone runs into this issue in the future.

I can share my old settings file if you prefer.
